![]() Instead, as part of a good BitLocker deployment plan, it is essential to think in advance about how to protect the VMK. ![]() However, you shouldn't care about these protection mechanisms only when problems occur. Key protectors are a central concept of BitLocker, and admins are regularly confronted with them when users are unable to unlock their computers. KeyProtectorId "Īlternatively, to remove all protectors of a specific type, use the following: manage-bde -protectors -delete c: -Type RecoveryPassword To remove a protector from a drive using PowerShell, enter this command: Remove-BitLockerKeyProtector -MountPoint "c:" ` The status displayed by manage-bde also contains an overview of the configured Key Protectors The status displayed by manage bde also contains an overview of the configured Key Protectors With this setting, you can allow, enforce, or deny the use of recovery agents, recovery passwords, and external recovery keys. For all three types of drives, there is a Group Policy setting called Choose how BitLocker-protected can be recovered. Microsoft recommends using a combination of Group Policy, PowerShell, and manage-bde to manage key protectors. Additionally, it requires a specific certificate, Windows Deployment Services, and a DHCP server. For this case, Microsoft offers BitLocker Network Unlock.Īdding the protector is just one part of the configuration. This can be an obstacle for remote management, where PCs boot up via Wake-on-LAN. Network UnlockĪuthentication with TPM and PIN requires physical access to the computer during startup or when it wakes from hibernation. Therefore, this technique is suitable, for example, when the helpdesk receives encrypted USB sticks from employees who have forgotten their respective passwords. The certificate for recovery agents must be stored in the local store of each computer on which you want to unlock a drive. They can only unlock system drives when the computer is booted from another disk, and system disks are accessed like data drives. Recovery agents are suitable only for data drives, not for system drives. Any other user logging into the computer will not have automatic access to the specified drive. The ADAccountOrGroup (also called SID) protector automatically unlocks a data drive when the configured groups or users from Active Directory are logged in. For example, one group may be 0.25 to 0.75 and another may be 0.5 to 0.25 on either side of the sticking points.Enable auto unlock for data and removable drives via BitLocker management Each set of numbers that you find will have the same range.A range of 22.5 and 23.5 would have a first sticking point of 23. A range of 4 and 5 would have a first sticking point of 4.5. Determine the first sticking point by finding the number that's in the midpoint of the sticking range.Some 800XXX and 908XXX locks have a 2-number sticking range (for example, 28 to 30 and 10 to 12).The CCW stopping point and CW stopping point from your sticking "range," for example, 22.5 to 10. ![]() Make note of the first counter-clockwise (CCW) stopping point. While continuing to apply tension to the shackle, turn the dial as far left (counter-clockwise) as you can.If so, record the number to the half (example: 22.5). Sometimes, the dial will stick right on the numbers, but sometimes the sticking point will be between the numbers. As you turn the dial CW with tension on the shackle, you will come to the first clockwise stopping point where you can't turn the dial anymore. ![]()
